The Great Wall of India. Yes, you heard that right. India has its very own version of the great wall in Rajasthan. This thirty-six-kilometer-long wall surrounding the Kumbalgarh fort is the second longest continuous wall in the world after its more illustrious peer in China. But unlike the Chinese great wall which is one of the most visited tourist attractions in the world, this one is puzzlingly not very well known outside the region. Even I was oblivious to this fact until I visited the fort, and it surely felt like I had stumbled upon one of India’s best-kept secrets!
